We shouldn’t name school and athletic team mascots after a race or group of people. And if a school is still clinging to the name, they are still clinging to the school song, attire, and cheers that belong to that culture.
I taught at a school with this exact same problem, and it was horrible how so many were A-Okay allowing us to continue to call ourselves the Indians and use all of those stereotypical elements that white people tie to the culture of indigenous peoples. The name isn’t some standalone thing with zero context attached to it.
